if you can get hold of the distance ed/open high school booklets, all your questions will be answered...my notes are under a pile somewhere so i can't really get them but you will find there is not a great deal of information on his childhood and education. i answered that question for an assignment and in an exam, and it amounted to not even a page for a full mark answer.
but the basic jist is that he was trained to be a warrior and a gardener...basic education consisted of training and learning to respect nature.
